SIGNAL AND EXHAUST CONTROL.

Specification of Letters Patent.

Patented Dec. 3,1912.

Application filed. February 2, 1907. Serial No. 355,383.

To all whom it may concern:

Be it known that I, EDWIN K. GoNovnR, a citizen of the United States, residing at Paterson, Passaic county, in the State of New Jersey, have invented certain new and useful Improvements in Signal andExhaust Control, of which the following is a full, clear, and exact specification.

My invention relates to improvements in motor vehicles, and the same has for its object more particularly to provide a simple, efiicient and reliable apparatus for controlling the discharge of the exhaust gases or products of combustion from the motor to the atmosphere through a mufller, or directly to the atmosphere without passing through the muffler in order to relieve any back pressure in the motor.

Further said invention has for its object to provide an apparatus by means of which the exhaust gases may be prevented from passing into the atmosphere either directly or indirectly through a muffler, and instead caused to pass into a signal apparatus in the form of a horn or whistle in order to operate the same.

Further said invention has for its object to provide mechanism for actuating said controlling means which is within easy and full control of the operator at all times.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described,

and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, wherein like numerals of reference indicate like parts, Figure 1 is a top view of a portion of a vehicle frame, and a signal and exhaust apparatus applied thereto, .constructed according to, and embodying my said invention; Fig. 2 is a section, taken on the line 2-2 of Fig. 1, showing the arrangement and construction of the operating levers; Fig. 3, is a side view, partly in section, of the apparatus as. seen in top view at Fig. 1, and Fig. 4 is a trans verse section taken on the line 4--4 of Fig. 1, and showing in front view a portion of the operating levers.

In said drawings 10 designates the forward portion of the metal frame of a motor vehicle and comprising the side members 11, 11, and an intermediate transverse member 12 from which extend forwardly the shorter longitudinal members 13, 13 which support the motor of the vehicle. Below said frame 10 adjacent to one of the side members 11 is arranged an exhaust pipe 14 which is connected at its forward end to the exhaust port of the engine, and at its rear end to the mufier which is usually rigidly secured to the frame. Intermediate its secured ends said pipe 14 is provided with a vertical casing 15 which may be made integral with said pipe or independent thereof and secured thereto, and has a screw cap 16 secured in its upper end, and its lower open end forming a valve seat upon which a valve 17 secured upon the end of a stem 18 is adapted to seat. The upper end of said stem extends through the cap 16 in the top of the vertical section 15. To the upper portion of the vertical casing 15 directly below the cap 16 is secured the end of a horizontal pipe 19 -which extends outwardly therefrom, parallel with the exhaust pipe 14, and 1s provided at its outer end with a whistle or horn 20. In the portion of the pipe 14 intermediate the vertical casing 15, and the muffler is arranged a butterfly valve 21, which is mounted upon a shaft 22 having one end extending through said pipe 14 and provided with a lever 23, and in the horizontal portion 19 intermediate the vertical casing 15' and the whistle or horn 20 is arranged a similar butterfly valve 24 which is mounted upon a shaft 25 having its corresponding end extending through said pipe and provided with a lever 26 which is connected at its lower end by a link 27 with the lower end of the lever 23 of the valve 21, in such a way that as one of said valves opens the other closes, and vice versa.

Within the channeled portion of the transverse frame member 12 are arranged shafts 28, 29 having their opposite ends supported in and extending through the shorter longitudinal frame members 13, 13. The shaft 28 has fixed thereon at one end an arm 30 having its outer end pivotally secured to the upper end of a link 31 which is pivot-ally secured at its lower end to the upper end of the stem 18 of the valve 17, and upon the portion of said shaft 28 between the frame members 13, 13 is secured by a key 32 the end of an arm 33 to the outer end of which is pivotally secured the lower end of a rod 34. The rod 34 is provided at its upper end with a detachable head 35, and intermediate its upper and lower ends it is pivotally secured to the forward end of an arm 36 which, at its rear end, works freely upon the shaft 29, and serves to maintain said rod 34 in a vertical position throughout its up and down movements. 37 denotes a coil spring which surrounds said shaft 28 and has one end secured thereto, and its other end secured to the frame member 12, and serves to maintain the rod 34 and its connected parts in a normally raised position. The shaft 29 has secured at its corresponding projecting end an arm 38, which is pivotally connected at its outer end by means of a link 39 to the upper end of the lever 26 fixed on the end of the shaft 25 of the valve 24. Intermediate the frame members 13, 13 upon said shaft 29 is secured a coil spring 40 having one end secured to said shaft and its other end to the frame member 13 in order to maintain said shaft and its connected parts to their raised positions. At the opposite end of the shaft 29 is secured by a key 41 the end of an arm 42, to the outer end of which is pivotally secured a rod 43 which is also provided at its upper end with a detachable head 44, and the lower end of said rod 43 is pivotally secured to the forward end of an arm 45 which is mounted at its rear end upon the shaft 28 so'as to work freely thereon, and thus serve to maintain said rod 43 in a vertical position throughout its up and down movements.

The operation of the apparatus is as follows: The apparatus, at Fig. 3, is shown in its normal working condition, and as here shown the exhaust passes from the motor through the pipe 14, thecasing 15, the open valve 21, and thence through the muffler (not shown) at the right hand end of said pipe, to the atmosphere. Should, however, the operator desire to discharge the exhaust gases directly to the atmosphere in order to avoid all back pressure on the motor it merely becomes necessary to depress, by foot, the rod 34 which will rotate the shaft 28, depress the arm 30 and cause the valve 17 carried upon the stem 18 to open and permit the exhaust gases to issue mainly from the lower end of the vertical casing 15. As soon as the pressure upon the rod 34 is removed the parts will be restored to their initial positions as shown at Fig. 3.

On the other hand, should the operator desire merely to operate the signal device 30, which may be a horn, whistle or analogous device, it only becomes necessary for him to depress the rod 43, thereby partially rotating the shaft 29, depressing the arm 38, link 39 and actuating the connected valve levers 26, 23, and thereby closing the valve 21 in the exhaust pipe 14 and opening the valve 24 in the pipe section 19 to which the signal device 20 is secured. As soon as thishas been done the exhaust gases will pass from the pipe 14 into the vertical casing 15, horizontal section 19 and into and through the signal device 20 and actuate the same. When the pressure upon the upper end of the rod 43 is again removed, the parts will be restored to their initial positions, as illustrated at Fig. 3. 7
